1.
The heat oxygen aging property and ozone aging property of clay/SBR and clay/NR nano-composites were studied,and the thermogravimetry and air isolation of clay/SBR nano-composite were also investigated.
研究粘土 /SBR及粘土 /NR纳米复合材料的耐热氧老化和耐臭氧老化性能 ,并考察粘土 /SBR纳米复合材料的热失重和气体阻隔性。
2.
Two adjustable CR vulcanizates to ozone aging at different conditions have been studied and results have shown tnat ozone concentration, force and deformation etc have clear effect on ozone aging Ozone aging at compression can also makc the vulcanizates produce crack and Thiol adjustable CR vulcanizate resistance to ozone aging is much better than sulfur adjustable CR vulcanizte.
通过对两种调节型的氯丁硫化胶在不同条件下的臭氧老化研究表明:臭氧浓度、受力状态、变形程度等对臭氧老化结果有明显的影响:压缩状态下的臭氧老化同样产生龟裂,硫醇调节型氯丁硫化胶抗臭氧老化性优于硫黄调节型氯丁硫化胶。

6)  accelerated ozone ageing
加速臭氧老化
补充资料:加速臭氧老化
分子式:
CAS号:

性质: 高分子材料在模拟强化大气臭氧的条件作用下产生的各种变化。臭氧是化学活性极高的物质,较分子氧更容易与含双键的高分子化合物发生化学反应。不饱和高分子化合物在应力作用下遇臭氧易产生垂直于应力方向的裂纹,称之臭氧龟裂。评价加速臭氧老化,通过臭氧老化试验进行。试验时使用臭氧老化箱,其臭氧浓度可分别为低、中、高三个范围。结果由试样外观、力学性能老化前后变化情况及龟裂程度等综合评价。
